Inflate Grid and CoordDim Retrieval Fixes
Inflate Grid and CoordDim Retrieval Fixes

The inflate grid was not returning the field because the np.take
function only gives a copy of the data (like fancy indexing).
Instead broadcast valid_data mask and then use this to set field
data.

The CoordDim returning masked full grid data doesn't really make
sense because we usually want that grid information. It now only
returns compressed grids, or full/flattened unmasked grids.
